I'm new to Limewire and was wondering how do I put downloaded music to a cd?

Welcome

You don't specify what OS you are using, but if it's windows you can use your mediaplayer to burn audio cd's. But Nero is better, instructions (Click Me)

If you don't have any burnprograms, just add files to WMP and burn from there

If you can afford it, Nero 6 is the best in my opinion. If you have Windows XP, it should come with burning software, providing you have a cd burner built-in.

Then you haven't tried Nero 7 Sphinx. With the new features it's a revolution in all-in-one technology
